Wampler Mofetta: A Modern Twist on the Mostortion MT10 Pedal Circuitry

🎛️ https://www.wamplerpedals.com/product...

In this video, we’re excited to introduce the newest release from Wampler Pedals: the Mofetta Overdrive/Distortion pedal. The Mofetta is built around the classic circuit topology of the Vintage Ibanez Mostortion, MT-10, but with a modern twist that brings new life to this vintage design.

The Ibanez Mostortion is known for its use of a MOSFET-based op amp and clipping diodes to achieve its unique overdrive sound. However, the Mofetta takes this concept further by having the ability of incorporating actual MOSFET gain stages instead of just relying on soft clipping diodes. This innovation brings a different texture and feel to the overdrive, making it a versatile tool for guitarists.

In the video, I start by discussing the inspiration behind the Mofetta. I explain the differences between the traditional Mostortion circuit and my new design, focusing on the use of MOSFETs for clipping. This method emulates the cascading gain stages found in tube amps, resulting in a more dynamic and responsive overdrive.

🎥 Here’s a breakdown of this video:

Introduction and Background: I explain the history of the Mostortion pedal and my motivation for creating the Mofetta. I touch on the high demand for Mostortion clones and my desire to offer something unique in the market.

Circuit Overview: I provide a detailed walkthrough of the Mofetta’s circuit blocks. The original Mostortion circuit uses a MOSFET-based op amp and clipping diodes, but the Mofetta adds MOSFET gain stages to enhance the clipping and overall tone. This results in a pedal that can switch between the traditional Mostortion sound and a new, crunchier MOSFET-based overdrive.

Sound Demonstration: I showcase the Mofetta through various settings, starting with the base Mostortion circuit and then switching to the MOSFET gain stages using the texture switch. This part highlights the pedal’s versatility, from subtle overdrive to more aggressive distortion.

Technical Details: I go into the specifics of the circuit design, explaining how the signal flows through the op amp and MOSFET stages. The use of low pass and high pass filtering helps shape the overall EQ, ensuring a balanced tone that suits a variety of musical styles.

Practical Use: I discuss how I personally use the Mofetta, emphasizing its capabilities as both a light overdrive and a high-gain distortion pedal. I also mention its popularity in Nashville for adding a bit of grit to clean tones.
